45lb. Mantus M2 - Improved. Test Video

- Mantus Anchor as submitted a second 45lb M2 anchor for testing. The first anchor had a small manufacturing flaw in the fluke that I theorized might have been the cause of some performance irregularities. Testing of the new, correctly built anchor should tell us just how much (if any) effect the flaw actually had on the anchor's performance.
That's great, I'm glad it seems like Mantus has tried to improve this flaw. Greg has always been very responsive, and it very much seems like he is into continuous improvement of his products.
Hi, thanks for all info and testing! I bought an 25 lb Mantus M2 and it fits perfect in the anchoring storage of my Jeanneau Sun 2000.
Great with a new episode! As recently as last night, I thought it's been a while since I saw you. In a few years I will buy a sailboat again and spend my retirement on board and sail around the world and the anchor is one of the most important safety accessories on board. Now I have something scientific to lean on when choosing anchors, not just the opinion of other owners, which is often that they have bought the right one. Many thanks for your fantastic job with great videos! Anders Sweden
That is impressive of Mantus. Continuous improvement in design is the name of the game.
Another great informative update. I used my 20lb Vulcan for the first time and anchored in 30’ of clean sand. I had a 5-1 scope with 30’ os SS 1/4” chain and 120’ of 1/2” nylon. The anchor set immediately and never moved during my short 1 hour anchorage. On retrieval with my windlass it took three tries to get it oriented properly to load on my bow rollers, a minor inconvenience. I chose the Vulcan as my anchor due to your hard work and the information you shared. If I am ever up in Washington and I run into you, lunch is on me 🍻
Thanks for the update.
Steve, interesting video. It looks to me as though the Mantus M2 will take the place of the Spade as spare bower of choice. I have a Vulcan as main bower and was thinking of carrying a dismantled Spade as the spare but now I’m thinking M2 as it dismantles, has at least as good performance as the Spade and it’s cheaper. All good. Best, Rob.
Excellent, useful information. And the crab-type animal wandering by at 10:38 looked amused as well.
04:35 going to the bottom with this anchor test is a good expression.
Thanks!
Great video!...again👏...
Hey Steve, still waiting on the kellet test. Thanks in advance!
Just rewatching this, thanks for your thorough testing Steve. I have a Mantus M1 that I purched years ago after studying your vids and it's proven to be very good and reliable in my neck of the woods. I had to wonder if the asymetery caused by the shank of the M2 pushing against one side of the fluke has any effect on performance. Could you shim either side and get it dead in the middle?
I have the 17lbs M2 but have held off buying the 45lb version due to Steve's test results. Great to hear Mantus have addressed the issues you identified. Well done Steve, well done Mantus that's a great relationship but are the anchors currently with stockists the old, imperfect anchors or have they been recalled and replaced by the new true made anchors?
Thanks for a great video. I see there is a couple of sixes in the chart now. I think comparing Aluminium anchors of the same weight as the steel versions would be interesting. Both weight and size are limiting factors sometimes one more than the other. When can i buy a 45lb Panope anchor ? ;)
Or the new Goodwin 60 lbs Athlete 😄
What about the back of the fluke, the tail wing is angled upwards when it should be pointing downwards? An upwards angle at back of fluke forces tip to point upwards when it is moving through the substrate, much like how an aeroplane’s wing flaps function. I recall the similar angle of the tail of the fluke of a rocna anchor had a similar effect until you hammered it flat causing a small improvement. Perhaps worth emailing Greg about this possible theory of why it rolls out!?
I am not so sure the "upturned trailing edge" is the cause of the roll instability. Note that two anchors with upturned trailing edges, (Vulcan, Spade) have excellent roll stability. Also, the Rocna (with upturned trailing edge) did not "roll" out. Rather, it "popped" out without rolling. Without spoiling the plot of my next video (# 134), be sure and tune in because I have found what may be another clue regarding roll stability.
@@flygoodwin I think you are mistaken, the Vulcan and Spade anchors have downward trailing edges. That said, I will certainly stay tuned for your next video! :-)
How do the ears help in this anchor? It is a completely new design however I haven’t heard much about the ears’ function.
When the anchor is on it's side, in the setting position, the ear will tend to elevate the rear of the anchor. This as the positive effects of shifting weight towards the tip/toe, and also presents the tip at a more favorable angle to the seabed. In other words, the ears help the anchor set.
@@flygoodwin I think the ears need a piece of metal welded onto them to stop them slicing down into soft mud and messing up the setting angle….
@@MrAthlon4800 Yes, an "ear flap" would have likely helped. I notice that virtually every other anchor design incorporates some sort of added metal in this area.
Thanks, Steve and Ross
At 10:58, was the anchor actually upside down?
To my eye, the anchor had rolled about 110 degree. So, while not 100% inverted, the anchor was certainly no longer right side up.

You are allowing too many variables in your tests. For example, the scope needs to be always the same, otherwise it's apples to oranges.
Scope is always 5:1 or 10:1 for all anchors as identified in the testing sheet at 15:32 not sure what you mean?
